Just got my new Cintiq 21ux this week....love it but when using Photoshop CS the lines are not smooth even when I use a ruler etc....have used a tablet for years so it's not practise but the software or something ???.....I do have smooth enabled in the Brush Dialog box so that's not the problem. When I sketch in Alias Sketchbook Pro and Corel Painter IX the lines are perfect and smooth.......Anybody have a similar problem and a solution.....any help would be appreciated...
Cheers Mike

PS
I have already turned off double-click distance and have the latest Wacom Cintiq driver version 6.05 installed
My operating system is Windows XP service pack 2

I've had a Cintiq for almost a year now and haven't experienced that, ever. The Wacom software doesn't dictate that sort of non anti-alias stuff. Are you sure you don't have a pencil (which gives stepped/hard edges) selected instead of a brush.

Thanks for the reply ;-) but it's not about the anti aliasing....I am indeed using a brush...have used Photoshop forever it seems......it's the line quality when you are sketching...the lines are almost wobbly looking like as if you are drawing drunk.......alas I am puzzed expecially as Painter and Sketchbook sketch lines are fantastically smooth...

All three images were sketched at the same speed motion etc.....only Photoshop is wobbly and have sketched for years so it's not skakey hands to blame etc.....at slower speed in Photoshop the results are more wobbly.....Just got feedback from Wacom and they say it's a Photoshop problem?

Hi Rob indeed I did read your post the CINTIQ 21UX is the tablet and monitor in one so I can't move it away from the monitor as it is the monitor....as you can see by the link below something is going on with Photoshop....(Painter and Sketchbook are fine)..I had an Intuos before and never had any line quality issues until I just got my new Cintiq setup......there seems to be a few people out there with the same issue with the CINTIQs and Photoshop just looking to find some answers....Cheers Mike

I also just got a Cintiq a few days ago and have noticed some issues in Photoshop regarding line quality...

Creativeboy have you noticed that if you flip the pen around to the eraser tip that the photoshop quality improves, I've got improved lines when erasing, but as soon as I flip it back over to the other side the poor line quality continues. This leads me to believe there is some kind of issue with the photoshop brushes maybe.. not sure, never had a brush issue before lol

Hi Scott.....just did a quick check on Photoshop and not really getting any better line quality by flipping the pen and using the eraser...... I never had an issue before with Photoshop either with my old Intuos tablet which I've had and used for almost 9 years......

Found a few more people who are having the same issue with Photoshop and their Cintiq 21UX.......do you use Painter or Sketchbook pro (or another drawing program) at all....is the line quality good in them on your Mac...

I'd definitely file an official bug report with Adobe about this, with a link provided to the DeviantArt page. That composite clearly shows there's a difference in stroke behavior. As long as you're sure you've eliminated stroke attributes as a cause, this is something that really should be fixed.

I've tried it on three different macs, one G5, two Mac Pro's (a quad and 8-core). As well as CS2 and CS3 varying between the three different macs, throughout all of them, the poor line quality has stayed the same.

I spent a good hour fiddling with brush settings changing everything I could think of to correct the issue, but so far, nothing.

Mike,

Looks like wacom wasn't much help... even more frustrating. I totally hear you about using photoshop the majority of the time. It's all I use essentially. Granted the application wasn't technically designed with tablets in mind compared to Sketchbook or Painter, but I still don't see why we can't come up with a solution either through Wacom or Adobe.

I've also noticed that when I'm zoomed in (200%) the line quality does improve, it's still not perfect compared to Painter, but it is a definite improvement. However inking at 200% isn't really a viable option.

wow this is interesting. I just purchased the new 12" Cintiq. I do a lot of inking in Illustrator (which works great yet of course Illustrator has smoothing options). My lines look bad in Photoshop which worked fine with my old ArtZ.

I'm having the same problem when drawing with the brush tool in CS3-- jagged lines. Not as bad as a bitmap file but pretty close. I know that lines look jagged at 33.3% and 66.7% of full size but they do not smooth out at 25%, 50%, etc like they should. Text looks bad too, even at 100%.

Perhaps you have the "snap to grid" feature enabled. Go to the View menu, click Snap To, and make sure Grid is unchecked. Also go to the View menu, click Show, and make sure "Grid" is turned off there. The snapping behavior should only happen when the grid is visible, but perhaps you've done something to the grid settings that is making it invisible for some reason.

This helped another user with similar complaints: http://www.adobeforums.com/webx/.3c06162f/1

Snap to Grid is off, snap to everything is off. And smoothing is checked. Neither help.

I do wonder, when i last used my intuos3 9x12 at my last job on CS, it worked fine. My new intuos 3 9x12 on CS or CS3 (mac or pc) gives the wobbly lines. What I have noticed is the tablet looks minutely different in places...in the way it is manufactured. The buttons for example have a large gap at the top which i didn't have last time.

What I am getting at is have wacom moved/changed their manufacturing facilities and for some reason these "newer" or "more recent" tablets have some quality issue/fault in them? I dont know, just the only thing I can think of, as this hasn't happened to anyone until recently, and now its happening to a large number of people.
